To all whom it may concern:

Be it known that l, HENRY A. Burns, a citizen of the United States, and resident of Corona, Long lsland,in thecounty of Queens and State of New York, have in vented a new and useful Improvement in Metal Boxes, of which the following'is a specification.

This invention relates to improvements in receptacles having removable covers, andmore particularly to sheet metal boxes each, fir instance, as shoe blacking boxes and the li e.

The object of the invention is to provide an article of this character which is very cheap to manufacture and which has a slip on cover that may be quickly and easily ap plied and removed, and which will firmly retain its proper position upon the receptacle and form a satisfactory closure therefor duringa very considerable p eriod ot use.

Another object is to provide certain improvements in the form, construction and arrangement of the several parts whereby the above named and other objects may be effectively attained.

A practical embodiment of my invention is represented in the accompanying drawin in which, be ig. 1 represents a side elevation otthe Fig. 2 represents a vertical central section therethrough, taken on the line Hlll of Fig. 1, looking in the direction of the arrows, and

Figs. 3, 4 and 5 represent enlarged detail sections showing the shape of the cover and its engagement with the box at different points of the circumference.

The box or receptacle is denoted by 1 and may conveniently be formed by stamping or drawing sheet metal. It is provided with an outwardly projecting head 2, near its top, which bead may be formed by a rolling operation or in any other convenient man ner.

The cover is preferably composed of some relatively springy sheet metal, such as tinned or lacquered sheet iron or steel. It comprises a flat bodyportion, denoted by 3, and a peripheral flange 4; which extends substantially at right angles to the body por tion 3. It will be noted that this fiange' 4: is bowed or rounded so that its lower part presents, throughout the major part of its wardly. Three of these ears are shown in the present instance and are indicated by 5,

6, 7. The ears 5' and 6 are similar and are each provided with a bellied or curved part '8, adapted to fit over the-bead 2, so'asto yielding-1y hold the cover on the box, as clearly shown'in Fig. l.

v The ear 7 includesa bellied or curved part l l similar to that of the ears 5 and-6', but it is projected in the form of a tail 9 whichv extends downwardly and outwardly from the box when the cover is in position thereon, in order to provide means for the manual removal of the cover.

The body 3 of the cover preferably has a depressed annular groove 10 formed therein and spaced a short distance from the periphery thereof. This groove takes the form of a ridge on the inside of the body.

portion 3 of the cover and, together with the inside of the flange ll, forms a seat for a suitable washer or packing ring 11, which may be composed of some material such as rubber, gum or other suitable composition.

It will be noted that when the cover is seated in position on the box, the washer or packing ring H is compressed slightly between the cover and the upper edge of the box, which latter is provided with a roll 12 which acts as a stiffening agent and also eliminates the unsightly appearance and scraping or cutting propensity of a straight raw edge of sheet metal.

In operation, the cover may be applied to the box by first sliding two of the ears down over the head 2 and then swinging the other side of the cover down into position, or it may be applied by a straight downward movement which causes all three of the ears to simultaneously engage the box.

The shape and resiliency of the flange 4 and ears 5, 6, 7, cause them to readily expand sufficiently to slip over and engage the bead til) 2; and it may be noted that this expansion of the ears in riding up on the head has 'a tendency to contract the flange intermediate of the cars so as to compress its edge firmly against the side of the box and thus assist in forming a tight closure and retaining the cover in position.

It will be understood that various changes may be resorted to in the composition, form, construction and arrangement of the several parts without departing from the spirit and scope of my invention, and henceI do not intend to be limited to the details herein shown and described except as they may be specifically included in the claims.

What I claim is:

1. An article of the character described comprising, a receptacle having an annular bead, a cover having a bowed depending flange, the lower edge of said flange being inwardly disposed and fitted to engage the upper side of said bead, and ears depending from the flange and having a curved portion arrangedto engage and conform to the bead.

2. An article of the character described comprising, a receptacle having a rolled upper edge and an annular bead spaced from said edge, and a cover having a bowed depending fiange, the lower edge of said flange being inwardly disposed and fitted to engage the upper side of said bead leaving a space between the rolled edge of the receptacle and the cover.

upper edge and an annularbead, spaced from said edge, a cover having a bowed depending flange, and an inwardly extending annular ridge spaced from the flange to form a channel for the reception of a packing ring, the lower edge of the flange being inwardly disposed and fitted to engage the upper side of said bead leaving a space between the rolled edge of the receptacle and the cover.

4. An article of the character described comprising, a receptacle having an annular bead, a zOi Ver having, a bowed depending flange, the loweredge of said flange being inwardly disposed and fitted to engage the upper side of said head, and ears depending from the flange andhaving a curved portion arranged to engage and conform to the bead, one of said-ears having a downwardly and outwardly extending tail to facilitate the manual removal of the cover.

In testimony, that I claim the foregoing as my invention, I have signed my name this sixth day of February, 1918.

HENRY A. BEYER.
